Background

on the way home from
Black Sheep Family Reunion

If you've been reading this blog for a while, there are a couple of things that have probably popped out. First, I've been wanting to get bigger tires since I did the engine/tranny swap. Second, our cars appear to break down in bunches so we rely on the bus as a "life raft" when one of the regular use cars fails. Until last Summer, this had been a fine pattern: when emergency struck, I'd abandon whatever project I was working on and drove the bus while fixing whatever was wrong with whichever car was broken. Last Summer on our trip to Wheeler (see Santa Clara by way of Wheeler), we lost a tire. This forced a tire replacement decision. I chose not to decide, and to instead take my chances and drive the bus as little as possible.

Rubber Ages

Wheeler

The current set on the bus is over 10 years old, and they spent most of their life sitting still. The tread is awesome, but the rubber is starting to break down. This is normal. To the consumer, hearing a tire salesperson explain that "while the tread looks good, your tires are dangerous" rings hollow. Most folks have the same immediate reaction: you're just trying to sell me tires I don't need. I know I think it. In truth, the oxidation of the rubber does cause it to become less capable of holding air. Eventually they develop slow leaks. In some cases the sidewall can become unstable and rather than frustratingly running flat, it could blow out. Yikes.

Research Leads to Solutions

mid- paint job, winter 2014

Since I'd been wrestling with this problem for a while, I had lots of research to depend upon when I had to make decisions (see: Wheels, Studs, Chrome and Backspace). Decision time was now. With 2dot0 gone (see Oh SNAP), Boo and I had to re-possess her old Saturn named Dude from the person we had long-term-loaned the car to. I haven't blogged much about Dude, but that car has been the cause of a fair share of life-boat emergencies. With our stable reduced by one, I needed Hapy back road ready right away. So, I hit craigslist, hoping to find some old 15" Vanagon rims. Instead, I found a set of 16" x 7" wheels with some 50/50 rubber on them.

I ran the current size rim/tire combination (215/60R16) through my spreadsheet. According to my calculations, I had less than 8mm between the edge of the rear tire and the rear fender, but otherwise it easily fit: 14mm away from suspension, over 40mm between the edge of the tire and the front/rear fender edge of the front wheel. Comfortable that these would fit, I bought them.

Acquisitions

new shoes, p-side

It turned out that the seller (name withheld to protect the innocent) knows my old friend Justin. The seller has a stable of Vanagons, including a mid-80' Subaru-powered Westy, a TDI-powered single-cab and a regular '87 7 passenger. I totally drooled over the Westy and the single-cab. The Westy is his wife's daily-driver (very impressive). I could have talked VW's and crawled over his Vanagons all evening, but the weather was for rot and he and his wife had dinner on the stove, so we traded cash for wheels and I hit the trailing edge of rush-hour traffic home.

Install
Changing a tire isn't exactly hard. Block opposite side wheels. Crack lugs. Raise vehicle until rubber no longer touches the ground. If possible, put a jack stand under frame for extra safety. Remove lugs. Remove wheel. Install is reverse, with final torque performed when the tire is back on the ground, "jumping the center" as you go. Doing this 4 times can take some time and energy. I think it took me 2-1/2 hours to do all four. Along the way, I convinced myself that the rear end has too much float to it. I had to raise the rear end too high into the air, I almost ran out of threads on the BusDepot jack, and the tire still wasn't off the ground. I resorted to putting a small rolly jack under the lower shock mount to get the wheel up. I have to address this rear suspension.

new front rim

The wheels fit over the rear castle nuts and front grease caps. In fact, there is a hair of room to put little covers over them to clean up the look. The rims, though, only had one cover included, so I'll have to find some. The original lugs fit, though it was tight. I was able to get them on with the tips of my fingers, and had to use a 3/8" driver with a socket to set them. The old spare that was put on in Wheeler went back onto the nose, for now. I'll need to replace that soon too.

I haven't had a chance to take a test drive yet. I am mid-way through a few projects, but I may clear the bus of half completed work so I can take a spin tonight. The wheels look great, IMHO. K, my oldest, says it has a throw-back beach bum look. I'll take it. I'll be replacing these tires when the need arises, and then I expect to put on 215/70R16 for a slightly lower revs-per-mile than the current set.

Thanks, as always, for following along.

Oh SNAP

A couple of weeks ago, I had the $500 Jetta suddenly stall in the driveway. Today's post covers the root cause investigation.

P0341: cam position sensor
P0422: o2 sensor

Stall

So, Boo is standing in the driveway next to her idling 2001 VW Jetta (named 2dot0) when it suddenly stopped running. There was no special noise, nor did it gasp on it's way down. It was just running one second and not running the next. My mind ran through a few scenarios, but I landed on electrical because of how quickly it shut off.

What You Should Do

Since a gas engine runs with the correct combination of fuel, air, compression and spark, These are the things that should be checked, and checked in that order, before you start swapping parts... even if you think you're sure you know what's wrong. If you have a more modern car, get a code reader and pull the codes from the computer. Sometimes, the computer won't give you a code for a while. I didn't get these codes here until after I'd figured out what was wrong through the steps below. The P0341 code confirmed my findings.

Fuel

fuel pressure regulators
(new on right)

Simply put, verify that you have fuel at the injector. To radically simplify things, I verified that I had fuel at the fuel pressure regulator by removing the regulator and letting the fuel pump cycle. I had fuel bubbling over. Pulling an injector can be difficult, so for me, this demonstrated that I had fuel at the rail. The probability of all 4 injectors clogging so badly that the fuel wasn't making it to the chamber was so low, I ruled out fuel, but replaced the fuel pressure regulator anyway since the old one fell apart on extraction (see picture).

Air

Check the air filter. It is completely clogged? It's probably not the issue. Check the "snow snorkel" that runs from the air box to the outside. Sometimes something can get jammed in there (like snow), preventing the engine from getting air. Remove some intake piping between the air box and the metal bits so you can see the little gate on the air intake. When the foot pedal is moved, does the flap move? You're probably getting air. This would be a good time to check the air sensor. This usually would throw a code, but to verify it isn't that sensor, unplug it and try to start the car. If it starts, that sensor is bad. The car will run without the sensor, but badly. Sometimes this sensor can prevent a start, but that wasn't the case with me. I ruled out air, and put everything back together again.

This is where I should have checked compression, but I was convinced it was an electrical thing, so I skipped ahead to Spark. Don't. Checking your compression is easy, and it reveals some very interesting info about your upper end, the mechanical timing and, possibly, a lower end issue.

Compression

2.0 ignition coil

Grab your compression tester (they are pretty cheap, if you don't have one) and test your cylinders one at a time. It's best to remove all four plugs, and test each cylinder multiple times. Take care how you manage your plugs and wires so you don't set yourself or your car on fire nor do you lose track of which wire goes where. Unplugging the coil is the simple solution. Anyway, if you get any reading under 100psi, try squirting a little oil into the cylinder and retest. If the reading is better, your rings are going and you'll need a bottom end rebuild soon. Start saving. If the reading doesn't change, its a valve-train issue. Assuming all of your reading are within 15% of each other and they are all above 100psi, move on to fuel.

Had I done this step before Spark, I would have found all 4 cylinders at 0 PSI, indicating a broken timing belt. This was verified by removing the timing belt cover and not seeing the belt. Yikes.

Spark

Remove the spark plug that's easiest to get to. In the 2.0 engine, that's #4. Take care how you remove the plug wire. Now, with a partner turning the key, hold the plug against the engine block (forming a ground) and watch for the spark. No spark? Could be your issue. I was way overdue for a tune up, and the plug socket fell off the plug wire when I touched it, so I concluded replacing plugs and wires was a good idea. 2dot0 still didn't start. I should already have checked compression, but still, I should have stopped here and gone back to it. I continued down the electrical gremlin path instead.

The new plugs and wires didn't do it. So, I got a new coil. And then a new battery. And finally a new crank position sensor. Still no start.

Realizations

no, I'm not a Packer fan

It wasn't until I got to this point that I reverted to the compression tests and learned that I had just thrown over $100 of new parts plus a battery into a large boat anchor. The timing belt broke, throwing off the timing and causing the valves to hit the piston tops. The engine was effectively blown. Tiny fragments of valve and piston will work their way into the deeper recesses of the engine while the breaking belt could have damaged rollers or the coolant pump. I sold the car for scrap and its gone.

Watching 2dot0 get towed away, I ran a quick accounting. I bought the car for $500, and had it running for another $30. Since then, I only bought tires and oil, so that's probably another $600 or so. Rounding up, I was probably into that car for $1200 before it broke and then threw another $300 into it. That's $1500 for a car including maintenance for 18 months minus the salvage I was paid, means it cost me less than $70/mo. Since you can barely rent a car for a weekend at that rate, I think we did extremely well. I just wish I had performed the timing belt maintenance.

That's all for today. After 2dot0 broke, I served my penance for not doing the timing belt by riding mass transit for a few weeks. Today was my first day back driving to work. It is such a luxury, though I do kind of miss the light rail. Thanks for following along-

Circus Circus, Tahoe and High Sierra Snow (part 3)

Continuing the travel saga from the last 2 posts. part 1 - flights & hotels. part 2 - Nevada. Now, for part 3, Colorado. I'll get to some bus/car content next time.

Welcome to Denver?

hotel room view

We arrived at Denver International on Sunday, about an hour before the Broncos hosted the Pittsburgh Steelers in a divisional playoff match-up, while the Seattle Seahawks / Carolina Panther game was still being decided. We asked an information booth about mass transit (nope), and then called the hotel about a free shuttle (nada). Our options, according to the hotel, were to grab a cab or take a airporter shuttle van, either ran $50. We saw a shuttle at the curb, so we approached for a ride. The driver was overtly unpleasant and short-changed me $10 for the displeasure. The van already had 5 other people in it, so we got ourselves a tour of Denver on the way into the city center.

Bouncing along, I was keeping up to date on the Seattle game and shared the play-by-play as it appeared on my phone. The rude driver picked up on the conversation and put the game on the van radio. It turned out that everyone in the van was good with Seattle losing. Ha. This created conversation, though, and soon we learned that one of our fellow occupants had a ticket to the Denver/Pittsburgh game waiting for her. We tried to convince her to go, though I think she may have skipped it for needed rest.

All That's Missing Are the Tumbleweeds

Erbert & Gerbert's

We got checked in, dropped our stuff in the room and immediately set out in search of some city energy and some food. The streets were dead. Seriously, I could have laid down in the middle of a 3-lane one-way street for 15 minutes and not blocked a car. We walked around Lower Downtown (LoDo), past the 16th Street Mall, and around. The only other people we saw were 2 couples who appeared to be on their way to a rodeo, complete with pretty hats and their thumbs tucked behind their oversized belt buckles. Neat. Denver is clearly more "western" than the cities further west. We stopped in at Erbert & Gerbert's Sandwich Shop, and the locals behind the counter explained the empty streets: football. If you weren't at the playoff game, you were in front of a TV watching it. This sandwich shop, apparently, was one of the few places around downtown Denver that didn't have a TV, so it also didn't have any customers. Except us. We ordered 1 each of two different suggestions from the counter guys (Flash & Comet Candy). They were really good. On our walk back to the hotel, we started seeing more people. There were a few kids skating on a mall ice rink, and a few patrons of the 7-11 on the corner. Concluding it was half-time, we made our way back in time for the end of the game. T's friend R and his dad were in town after visiting UCD the day before, so we visited with them a little bit.

Colorado State University

We had allotted Monday, MLK Jr Day, to wander around Denver. After we got back to the hotel, T indicated that he'd seen enough to get a sense, between the long shuttle and couple of hours of walking. Instead, he wanted to see Colorado State University (CSU) in Fort Collins. Recognizing the upside of not over-scheduling things, I rented a car for the next day on the spot. The drive between Denver and Fort Collins is a straight-arrow shot up I-25 for about an hour. CSU was mostly closed for the holiday, but we were able to get into the art building and poke around. The building was small, but the students seemed very invested. Even on their day off, they were milling around, drawing and hanging out. Based on the installations, the multiple kilns and posters, the community looked very vibrant. Similar to UNR, there was considerable construction going on, and we had a hard time figuring out what was where. That morning, we had left Denver in a bit of a rush, and failed to eat anything, so by 2:PM, we were starving and couldn't think about schools any more. We stumbled upon Aloha Coffee and Grill. Coming from the west coast, my expectations for Hawaiian are pretty high, and Aloha didn't quite make it. The coffee was good, though. T left CSU glad we visited, but not too interested: far from snow and travel, but looked like some great programs. The drive back to Denver was highlighted by the discovery of the funniest convenience store name we'd ever seen: the Loaf 'n' Jug.

University of Colorado, Denver

CO has Rockies, but is also flat

Tuesday was our last day of the trip, and it was time-crunched. We had a tour at 10, had to check out by noon and had a 4:PM flight home. That's tight. We readied for the day, packed up the room and hit the coffee shop in the lobby (learned from yesterday) for some breakfast. Walking to the campus was only a few minutes away, so we were early for the tour. Unlike UNR on Thursday, this tour group was bigger, and the campus was having its first day of classes after winter break. It was teaming with people. The guide pointed out that this first week everyone comes in to get schedules, ID's, etc, so it was unusually busy. UCD is a commuter school with limited on-campus housing options. Still, there are dorms, and for a location, it's prime. The Pepsi Center, Coors Field, Mile High Stadium and all of LoDo is right there. Unfortunately, the school shares a campus with 2 other educational institutions, and it hasn't any sports teams, reducing the sense of community. The mostly-commuter student make-up further erodes that sense. There are lots of internship and corporate-placement opportunities, though, so for the prospective student who wants a degree and then a direct path into corporate America, UCD is a great option.

Homebound

CSU construction map

We detoured into Which Wich for a go sandwich on our way back to the hotel. They have an interesting model: your order slip is the paper bag in which your wich is placed and then given to you. Clever. And a pretty good wich too. We cleared out, checked out and walked across the street to the taxi stand where a line of cabs awaited. Now that the game was over and business had resumed, the streets were bumping again. Still, we had a quick and informative ride into the eastern plains where Denver International Airport awaited. Our cabbie had lived in Portland, so we talked about the marijuana legalization parallels and local music comparisons. T and I easily passed through ticketing, security and boarding. After 6 flights in as many days, we'd gotten pretty efficient at it. Boo met us at PDX, grinning at our huge smiles when we picked her out of the car queue.

We had a great trip. We saw 3 universities, visited with family and friends and tasted some snow. Most importantly, T had made his decision about which school was his first choice: UNR. He has learned since this trip that he was accepted, and so he is going through the process of determining costs so he can commit. Go T!

As always seems the case, there have been lots of things going on with cars, and such both before and after this trip, so I'll post on some of that here soon. As always, thanks for following along and Hapy Saint Patrick's Day!
